Product details
Overview
MSP430F47197IPZ from Texas Instruments is an ultralow-power mixed-signal microcontroller designed for poly-phase electricity metering applications. It integrates seven 16-bit sigma-delta ADCs with differential PGA inputs, 120KB Flash/4KB RAM, a 16-bit RISC CPU, integrated LCD driver (160 segments), four USCI modules (UART/IrDA/SPI/I²C), and operates from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F47197IPZ datasheet, MSP430F47197IPZ pinout, MSP430F47197IPZ application, or MSP430F47197IPZ equivalent, key selection criteria include sigma-delta ADC channel count, LCD segment drive capability, low-power mode timing (sub-6 µs wake-up), and QFP-100 package compatibility for metering board layout.
Technical Context
The MSP430F47197IPZ implements a 16-bit RISC CPU with constant generators and 62.5-ns instruction cycle time, paired with three-channel internal DMA for high-efficiency data movement between its seven SD16_A sigma-delta converters and memory. Its FLL+ oscillator enables fast wake-up (<6 µs) from LPM4, critical for real-time energy measurement sampling.
It features dual analog supply domains (AVCC/AVSS) and dedicated sigma-delta input pins (A0.0± through A6.0±), with all seven ADC channels supporting programmable gain and differential input pairs - directly enabling simultaneous voltage/current sensing across three-phase systems without external signal conditioning.

FAQ
What is the maximum number of differential analog inputs supported by the MSP430F47197IPZ?
The MSP430F47197IPZ supports seven independent differential analog input pairs (A0.0± through A6.0±), each connected to a dedicated 16-bit sigma-delta ADC channel. This configuration enables simultaneous acquisition of voltage, current, and auxiliary signals in three-phase metering systems without external multiplexing or signal conditioning circuitry. All seven channels are accessible and functional on the MSP430F47197IPZ device.
Does the MSP430F47197IPZ include an integrated LCD driver, and how many segments can it drive?
Yes, the MSP430F47197IPZ includes an integrated LCD_A module capable of driving up to 160 segments. It supports static, 2-mux, 3-mux, and 4-mux configurations using dedicated segment (S0–S39) and common (COM0–COM3) pins. Contrast is adjustable via software-controlled internal charge pump, eliminating the need for external bias generation components in meter display designs.
What low-power modes are available on the MSP430F47197IPZ, and what is the lowest current draw?
The MSP430F47197IPZ offers five software-selectable low-power modes (LPM0–LPM4). In LPM4 - the deepest sleep mode - it draws only 0.2 µA while retaining full RAM content, enabling years of operation on coin-cell backup power. Wake-up from LPM4 to active mode occurs in less than 6 µs, ensuring precise timing for periodic metrology sampling without sacrificing energy efficiency.
Which communication interfaces are integrated into the MSP430F47197IPZ, and are they configurable for standard protocols?
The MSP430F47197IPZ integrates four Universal Serial Communication Interface (USCI) modules: USCI_A0 and USCI_A1 support UART, IrDA, and SPI; USCI_B0 and USCI_B1 support I²C and SPI. These are fully configurable for industry-standard protocols including DLMS/COSEM over UART, optical probe interfaces via IrDA, and sensor communication over I²C - all without external transceivers.
Is the MSP430F47197IPZ pin-compatible with other devices in the MSP430F471xx family?
Yes, the MSP430F47197IPZ uses the same 100-pin QFP (PZ) package and shares identical pin assignments with all MSP430F471x7 variants, including MSP430F47127IPZ, MSP430F47167IPZ, and MSP430F47177IPZ. Pin compatibility extends across all x3/x6/x7 subfamilies in the PZ package, allowing flexible migration based on Flash/RAM/ADC count requirements without PCB redesign.
